| 20090120859 | Water aerating and dirt collecting assembly for aquarium - A water aerating and dirt collecting device for an aquarium includes a pumping device having a paddle device for pumping and circulating the water contained within the aquarium, a receptacle having an entrance coupled to the pumping device for receiving the water from the pumping device and for agitating the water and for generating an eddy current, and a casing having an inlet port coupled to the receptacle for receiving a filtered dirt from the receptacle and having a mouth coupled to the pumping device for allowing an air in the casing to be drawn into the pumping device. The receptacle includes a tubular member for collecting the filtered dirt. | 05-14-2009 |
| 20090120860 | Water aerating and dirt collecting assembly for aquarium - A water aerating and dirt collecting device for an aquarium includes a pumping device having a paddle device for pumping and circulating the water contained within the aquarium, a receptacle having a three housing members coupled to the pumping device, a vessel disposed on an upper housing member and having a tubular member for forming a peripheral chamber and for allowing an air bubble and a dirt to flow upwardly through the tubular member and to be collected in the peripheral chamber of the vessel, a cap attached to the vessel and having an exit coupled to a dirt collector for collecting the dirt, and having a mouth coupled to the pumping device for vacuuming purposes. | 05-14-2009 |
| 20090126645 | Dirt collecting device for aquarium - A dirt collecting device for an aquarium includes a housing disposed on an apertured floor plate, a barrel disposed on the housing, a casing disposed on the barrel and having one or more openings for allowing the water form the barrel to flow into the aquarium, the casing includes a tubular member for forming an annular chamber between the tubular member and the casing, and an exit communicating with the annular chamber of the casing, and an air supplying device may supply air bubbles into the housing to carry the dirt and to move the dirt upwardly over the tubular member and collected in the annular chamber of the casing for allowing the dirt to be easily removed. | 05-21-2009 |
| 20090127175 | Water aerating device for aquarium - A water aerating device for an aquarium includes a pumping device having an impeller for pumping a water, a receptacle attached to the pumping device, a tube disposed on the pumping device for forming an annular space between the receptacle and the tube which has a bore for supplying the water toward the impeller, a tubular member extended in the receptacle for forming an annular chamber between the tubular member and the receptacle and an annular passageway between the tubular member and the tube, and for allowing the carbon dioxide to be drawn into the tube and to be recycled and to be minimized into a large amount of smaller air bubbles. | 05-21-2009 |
| 20090127724 | Water aerating and controlling assembly for aquarium - A water aerating and controlling assembly for an aquarium includes an aerating device for attaching to a container of the aquarium, a gaseous reservoir coupled to the aerating device for supplying a gaseous material to the aerating device, and a controlling device for controlling the gaseous material to be selectively supplied to the aerating device when the gaseous reservoir is opened, such as during the day time, and for allowing an air or oxygen in an environment to flow into the aerating device and to be supplied to the water plants or the water weeds when the gaseous reservoir is closed, such as during the night time. | 05-21-2009 |
| 20090134532 | Aerating device for aquarium - A water aerating device for an aquarium includes a carrier, a pumping device attached to the carrier and having a motorized impeller for pumping a water, a siphon tube coupled to the pumping device and having a tube member engaged into the aquarium for allowing the water to be drawn into the siphon tube and drawn into the carrier by the impeller, and a number of rods disposed in the carrier for agitating the water and for minimizing an air contained in the water into smaller air bubbles. One or more air minimizing devices or helical spring members may further agitate the water and minimize the air contained in the water for supplying the reduced air bubbles to the water plants or the water weeds. | 05-28-2009 |
| 20090139458 | Aerating or air bubble collecting device - An aerating device for an aquarium includes a carrier, a pumping device attached to the carrier and having a motorized impeller for pumping a water and for minimizing the air in the water into a number or reduced air bubbles, a siphon tube coupled to the pumping device and having a tube member engaged into the aquarium for allowing the water to be drawn into the siphon tube and drawn into the carrier by the impeller, and a partition engaged into the carrier and having a passage for collecting the bubbles, and a receptacle disposed above the passage of the partition for receiving and collecting the bubbles and the dirt or protein carried by the bubbles. | 06-04-2009 |
| 20090139916 | Filtration device for aquarium - A filtration device includes a carrier for attaching to the aquarium and having a filtering chamber for receiving a water, a filter member disposed in the filtering chamber for filtering the water, and a signal generating device for generating a signal to indicate whether the filter member has been blocked or not or when the filter member may no longer filter the water contained within the container of the aquarium, and for allowing the filter member to be cleaned or changed or replaced by the user right away or when required. A dirt collecting device may be used to collect the dirt carried by the upwardly flowing bubbles. | 06-04-2009 |
| 20090255480 | Filter device for aquarium - An aquarium includes a filter housing disposed in a container, the housing includes a number of spaced guide fins extended into the housing and arranged to form a peripheral passage around the guide fins, a filter member engaged in the guide fins, and a water pump attached to the housing for pumping the water into the passage of the housing and for guiding the water to flow through the guide fins and to flow from various directions into the filter member and for allowing the water to be guided to flow through an outer peripheral portion of the filter member and for preventing the water from flowing through only a small portion of the filter member and for preventing the filter member from being quickly blocked by dirt or contaminant. | 10-15-2009 |
| 20090308325 | Temperature control device for aquarium - An aquarium includes a receptacle having a chamber for receiving a water, a temperature control device having a heater coupled to a processor device for heating the water contained in the receptacle, a temperature detector for detecting the water temperature, a displayer for showing the detected water temperature, and a remote control device having a receiver coupled to the processor device and a signal emitter for being operated by a user to emit a control signal to the receiver and to actuate the processor device to operate the heater and to determine the required water temperature and to prevent the user from contacting the temperature control device for the aquarium. | 12-17-2009 |
